Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic consolidation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3256XL-12TQG144I | 12 ns propagation delay; otherwise identical architecture, pinout, and voltage specs | Suitable where timing margin allows relaxed delay; lower power at same frequency | Select when system timing budget permits 2 ns relaxation and lower dynamic power is prioritized |
| XC95288XL-10TQG144I | 288 macrocells; same 10 ns speed grade but larger logic capacity and different pin assignment for I/O banks | Better suited for designs requiring >256 macrocells; not pin-compatible | Choose when additional logic density is needed and board layout can accommodate revised I/O mapping |
Compared with XCR3256XL-10TQG144I, the -12 variant trades 2 ns speed for reduced power, while the XC95288XL offers higher density at same speed but requires PCB redesign due to non-identical pinout and bank configuration.

FAQ
What is the maximum operating frequency supported by the XCR3256XL-10TQG144I?
The XCR3256XL-10TQG144I has a 10 ns maximum propagation delay, enabling reliable operation up to 100 MHz for registered logic paths. Actual system frequency depends on design topology, register placement, and routing congestion - verified timing analysis must be performed using Xilinx WebPACK or ISE tools targeting the XCR3256XL-10TQG144I device model.
Does the XCR3256XL-10TQG144I support in-system programming via JTAG?
Yes, the XCR3256XL-10TQG144I fully supports IEEE 1149.1 JTAG in-system programming. This allows configuration bitstream updates and reprogramming directly on the target PCB without removing the device, using standard JTAG adapters compatible with Xilinx programming software.
Is the XCR3256XL-10TQG144I RoHS compliant?
Yes, the XCR3256XL-10TQG144I is RoHS compliant and lead-free. The "G" in the suffix denotes green (halogen-free) packaging, and the device meets EU Directive 2011/65/EU requirements for restricted hazardous substances.
Can the XCR3256XL-10TQG144I operate at 2.5 V I/O voltage?
No, the XCR3256XL-10TQG144I is specified only for 3.3 V operation. Its I/O buffers are designed for LVTTL/LVCMOS 3.3 V signaling and are not tolerant of 2.5 V supply or interface levels. Using 2.5 V may result in incorrect logic thresholds or damage.
What development tools support the XCR3256XL-10TQG144I?
XCR3256XL-10TQG144I is supported by Xilinx ISE Design Suite 14.7 and earlier versions. Synthesis, place-and-route, and bitstream generation are fully validated for this device. WebPACK edition provides free licensing for this CPLD family, including simulation and JTAG programming support.
